<h2>Member Function Documentation</h2>
<!-- $$$id[overload1]$$$id -->
<h3 class="fn"><a name="id"></a><span class="type">int</span> TouchPoint::<span class="name">id</span> () const</h3>
<p>Returns the id number of this touch point.</p>
<p>Id numbers are globally sequential, starting at zero, meaning the first touch point in the application has id 0, the second has id 1, and so on.</p>
<!-- @@@id -->
<!-- $$$isPrimary[overload1]$$$isPrimary -->
<h3 class="fn"><a name="isPrimary"></a><span class="type">bool</span> TouchPoint::<span class="name">isPrimary</span> () const</h3>
<p>Returns true if this touch point is the primary touch point. The primary touch point is the point for which the windowing system generates mouse events.</p>
<!-- @@@isPrimary -->
<!-- $$$lastNormalizedPos[overload1]$$$lastNormalizedPos -->
<h3 class="fn"><a name="lastNormalizedPos"></a><span class="type"><a href="qpointf.html">QPointF</a></span> TouchPoint::<span class="name">lastNormalizedPos</span> () const</h3>
<p>Returns the normalized position of this touch point from the previous touch event.</p>
<p>The coordinates are normalized to the size of the touch device, i.e&#x2e; (0,0) is the top-left corner and (1,1) is the bottom-right corner.</p>
<p><b>See also </b><a href="qtouchevent-touchpoint.html#normalizedPos">normalizedPos</a>() and <a href="qtouchevent-touchpoint.html#startNormalizedPos">startNormalizedPos</a>().</p>

<p>Returns the scene position of this touch point from the previous touch event.</p>
<p>The scene position is the position in <a href="qgraphicsscene.html">QGraphicsScene</a> coordinates if the <a href="qtouchevent.html">QTouchEvent</a> is handled by a QGraphicsItem::touchEvent() reimplementation, and identical to the screen position for widgets.</p>
